I've made a partial fix:
trunk/src/target/u-boot/patches/early-powerdown.patch
Since this is experimental, it's not in
trunk/src/target/u-boot/patches/series. It should be placed between
uboot-20061030-neo1973.patch and uboot-s3c2410-misccr-definitions.patch
What it does: at the earliest opportunity, it checks if the phone was
woken up by the power button of an RTC event. If not, it powers down
immediately. This can be skipped by pressing the AUX button (e.g., if
you want to do just a software or hardware reset).
This gets the board out of the 1.2 and 0.6 second cycles. It doesn't
help against the 120 ms cycle, but that one may actually be just an
artefact of my test setup.
Unfortunately, this hack conflicts with the idea of powering up the
phone when a charger/PC is connected, so that the phone can request
500 mA from the USB host, instead of the meager 100 mA it gets by
default.
